From: Jin Yao
Date: Wed Feb 19 2020 - 20:36:57 EST
When performing "perf report --group", it shows the event group information
together. By default, the output is sorted by the first event in group.
It would be nice for user to select any event for sorting.
The patch 1/3 introduces a new option "--group-sort-idx" to sort the
output by the event at the index n in event group.
The patch 2/3 creates a new key K_RELOAD to reload the browser.
The patch 3/3 supports hotkeys in browser to select a event to
v6 was posted two months ago and all comments were fixed.
v7 just rebases to perf/core, no other change.

perf report: Change sort order by a specified event in group
perf report: Support a new key to reload the browser
perf report: support hotkey to let user select any event for sorting
